23 Jul What is a pollen count and how is it related to allergies?
A pollen count measures the amount of pollen in the air. They are sometimes mentioned or even shown in weather reports and are usually reported for mould spores and 3 types of pollen: grasses, trees and weeds. The count reports the number of pollen grains per square meter of air collected over a 24 hour period and is measured as absent, low, medium or high.
When the pollen count is low – it usually means that only people who are extremely sensitive to pollen will experience allergy symptoms while if it is reported as high, it means that most people with any sensitivity to pollen will experience allergy symptoms.
